(a) Construct a confusion matrix to show the model’s performance on this ‘fitted’ data. What is the apparent error rate (APER)?
(b) Subsequent to formulating the discriminant model DiscRim launch 5 more products (A, B, C, D and E) and use the model to predict “success” or “failure”.
The variables associated with these 5 products (and whether they actually turn out to be a “success”) are given below. They decided to launch these 5 products
anyway.
